The best thing about these Mons Lavabo concept sinks isn't their charming, monster design. It's that they're eco-friendly, promising to prevent children from wasting water. So just how does that work?

When a child begins washing their hands, the sink calmly advises them to, "HURRY UP YOU LITTLE FUCKER OR I WILL BITE YOUR FUCKING HANDS OFF AND CHEW YOUR BONES RIGHT IN FRONT OF YOU! YOUR LITTLE ARMS WILL BLEED ALL OVER THE PLACE, SPILLING OUT MY MOUTH AND ONTO THE FLOOR. YOUR DEATH WILL COME SLOWLY AS YOUR PERCEPTION PAINFULLY FADES TO GREY AND THEN BLACK—BY THE WAY, YOU WON'T BE GOING TO HEAVEN BECAUSE THERE'S NO GOD, SO YOUR BODY WILL JUST ROT IN THE GROUND AS EXISTENCE AS YOU KNOW IT CEASES FOR AN ETERNITY YOU'LL NEVER SEE. AND DON'T EVEN GET ME STARTED ON WHAT DAD WILL SAY WHEN HE SEES THE MESS YOU MADE! WHAT A FUCK UP! NO WONDER YOUR PARENTS ARE GETTING A DIVORCE! WHAT? THEY DIDN'T TELL YOU? WELL STOP YOUR GODDAMN CRYING ABOUT IT, TEARS ARE A WASTE OF PRECIOUS WATER!"
